The c mveyfir comprisws & w 7 usziwss chains 14 having cross links If: ai equidistaut intervals from which links the trays 16 are suspended. The chains are carried on sprockefpak's 17 mounted above the 101$ miller and are rotated in #:iackw e directiml apparatus havin means, such as the beveled gears 22, by wiich the Worm is turned.

riving means, preferably comprising the sprocket 23 fastened to the shaft 20 and connected by the chain 24 with the sprocket 25 on the camshaft 10, are provided to to tate the cams 9 in correct differential time relation to the rotation of the conveyor.

As any of the trays, for example the tray A, comes to a position opposite, to the outer end of the frame, while the latter is in the initial position shown in El l, the lirst row of shingles or strips wil be deposited thereon. Now as the tray continues its downward movement the frame will tilt downwardssynchronously therewith, but at a slower rate of speed, so as to permit the belts 3 to deposit a predetermined lllllllbtli of units in stacks or piles on the tray, a backing plate being provided to assist in properly stacking the articles. When the tray is loaded the frame will return to its initial osition in readiness for the succeedin eye e of operation.

he loaded trays are carried around to the rear of the conveyor where the stacks are removed by the workmen. To facilitate removal of the stacks the trays are preterably formed with hand-openings 27 in their rear edges as shown in Fig. 2.

In operating with certain classes of articles, such as individual shingles, l have found that the stacking is improved by slightly tilting the trays while they are receivin their charge. To this end I have provi ed guide-ways 28 on which the pins 29, fastened in the ends of the trays, ride. If desired the guides may be omitted.

Various changes or modifications in the details of construction and arrangement of parts herein-described may be resorted to without departing from the scope or spirit of my invention.

What I claim is:

1. In apparatus of the character described, a vertical band conveyor carrying equall spacedv receptacles, a frame pivoted to roc on a horizontal axis and having, a free end disposcdodjacent to the downward reach of the conveyor, endless belts extending longitudinally of the frame, actuating means operative to tilt the frame synchronously with a portion of the downward travel of each successive lccl'plzu'lo but at a slower rate of motion, and means lor restoring the frame to initial position between successive operations.

2. In apparatus of the character described, a vertical hand conv yor carrying equally spaced rm'cptaclvs, :1 frame pivoted to rock on a horizontal inis and having a free end disposed adjacent to the downward reach of the conveyor. rndless bulls i-xlemh ing longitudinally of the frame, actuating means operative to tilt the frame synchronously with a portion of the downward travel of each successive receptacle, resilient means for restoring the frame to initial position between successive operations, and cushioning means to check rebounding of the frame.

3. In apparatus of the character described, a vertical hand ronveyor carrying equally spaced receptacles, a backing plate parallel and adjacent to the rear edges of the receptacles on the downward reach. a framev pivoted to rock on a horizontal axis and having a free end disposed adjacent to said downward reach, endless bells calending longitudinally of the frame, actuating means operative to tilt the frame synchronously with a portion of the downward trawl of each successive receptacle but at a slower rate of motion, and means for restoring the frame to initial posit ion between successive operations.

4. ln apparatus of the character dc scribed, a vertical band conveyor carrying a series of horizontally suspended receptacles, guidcways for tilting the receptacles while traveling on the downward reach, a frame pivoted to rock on a horizontal axis and having a free end disposed adjacent to said reach, endless belts extending longitudinally of the frame, actuating means 0pcrative to tilt the frame synchronously with a portion of the downward travel of each successive receptacle but at a slower rate of motion, and means for restoring the frame to initial position between successive operations.

5. In apparatus of the character described, a vertical band conveyor, :1 frame pivoted to rock on a horizontal axis and havmg a free end disposed adjacent to the downward reach of the conveyor, endless belts extending longitudinally of the frame, cams operative to tilt the frame, and means for rotating the cams in correlation with the rotation of the conveyor but at a differential rate of speed.

6. In apparatus of the character dcscribed, the combination of a vertically movable substantially horizontal receptacle. and an endless belt convcyor movable angularly in correlation with the downward movementof the receptacle for depositing SUC- cessivcly a plurality of orliclcs thcrcon.

8. in apparatus of the vliui'm'ior described, the combination of a conveyor comprising a series of horizontally moving endess belts, a second conveyor comprising a pair of vertically moving endless chains carrying between them a series of suspended trays and a third conveyor comprising an anguarly movable frame carrying a series of endless belts disposed in alinement with the belts of the first-mentioned conveyor, the third-mentioned conveyor being arranged to receive articles from the first-mentioned conveyor and to stack them on the trays of the second-mentioned conveyor.

9. In apparatus of the character described, the combination of a conveyor comprising a pair of vertically moving endless chains carrying between them a series of suspended trays, and means for stacking articles upon said trays comprising an an larly moving band conveyor having its 51 live end arranged to follow the downwar motion of each successive tray through a predetermined portion of said motion but at a slower rate of speed EDWARD T.
